Subject: [PATCH 5/8] mips irq: update mips for new irq_desc
Date: Mon, 12 Jan 2009 14:05:24 -0800 [thread overview]
Message-ID: <20090112220520.303833000@polaris-admin.engr.sgi.com> (raw)
In-Reply-To: <20090112220519.566749000@polaris-admin.engr.sgi.com>
[-- Attachment #1: irq:update-mips-to-new-irq_desc --]
[-- Type: text/plain, Size: 2492 bytes --]
Impact: cleanup, update to new cpumask API
Irq_desc.affinity and irq_desc.pending_mask are now cpumask_var_t's
so access to them should be using the new cpumask API.
